    I've had my Mini since launch. On two occasions, after reboot, I've noticed flickering every few seconds on the bottom 1/4 of my screen. The second episode also seemed to have bright pixels that showed up randomly in the top 3/4 of the screen. Checked connections while Mac was on - I'm using the included HDMI to DVI connector. Monitor is same one I've use with my Macbook for years. Both times it was fixed with a restart. Not sure what this means or if anyone else has had it happen. If it was occurring more regularly, I would use the display port to DVI connector that I bought by mistake and try to see if that made a difference...

    NEC MultiSync 20WMGX
    Looks like it was released in 2006 :eek: Can't remember having it that long...
    Again, this was never an issue before and seems to be transient

    I've had this, but I've been havign problems routing HDMI through my amp (nothing else has problems) so thinking it might be related to that.

    Yamaha 767, base model mini.

    Also the mini has just come out of sleep, don't know if there is a handshaking issue there? No idea why the mini as default has such extreme power saving setup?

    Funny, I experienced the same thing, just once though. Bottom quarter of the screen was flickering once every 10 seconds, and then it slowly got more often, and flickering more of the screen. I rebooted and haven't seen it happen since.. Using a Dell 2407 screen with the hdmi-dvi adapter..

    could you tell me which model/graphics do you have? HD3000 or AMD? SmaugG5's should be HD3000 since it's a server, but it sounds like a different problem from OP's. I wonder if this is hdmi related or graphics card related? Ordered base model, now worried about this issue.
